E. B. CINTRON LADYS HEEL Feb. 8, 1944.

Filed Aug. 26, 1943 Patented Feb. 8, 1944 UNITED STATES PATENT OFFICE LADYS HEEL Ezequiel B. Cintron, New York, N. Y. Application August 26, 1943, Serial No. 500,035

4 Claims.

This invention relates to heels for shoes and more particularly for ladies shoes.

As is well known, heels are worn down unevenly and generally the rear of the heel will wear first with the result that th heel becomes dangerous to health and body and also becomes unsightly. This is especially true of ladies shoes because the heels of such shoes usually taper to a very narrow wearing surface. Ordinarily such damaged heels must be repaired by skilled workman, which is costly and oftentimes inconvenient and time consuming.

It is an object of my invention to provide a ladys shoe with a heel having a lift with a wearing surface which can be easily removed when worn.

Another object is to provide such a heel with a lift that can be easily attached by the wearer of the shoe, without the need of either skill or tools.

A further object is to provide means for readily securing the lift on th heel without the use of tools.

My improved heel is shown in the accompanying drawing in which- Fig. 1 is a perspective view of a ladys shoe having a heel embodying my invention.

Fig. 2 is a similar view with the lift in detached position ready for mounting on the heel.

Fig. 3 is a bottom plan view of the heel.

Fig. 4 is a plan view of the main heel portion.

Fig. 5 is a bottom plan view of the lift portion.

Fig. 6 is a sectional view on the plane of the line 6--6 of Fig. 3.

Fig. '7 is a sectional view on the plane of the line 1-4 of Fig. 3.

The shoe [0 shown is a ladys shoe and is provided with a high or Cuban type heel ll. As is well known such heels vary in size and some having a wearing surface as small as one inch in diameter. Such heels generally wear down at the rear and to one side, in the zone to the left of the line :r-:c in Fig. 1. Such a wearing zone will be on opposite sides in right and left shoes.

According to my invention, I provide a detachable lift l2 which when its wearing surface 13 becomes worn can be easily removed from the heel II and replaced with a new lift by the wearer.

The upper surface of the heel has a replaceable metal central stud l4 projecting outwardly therefrom. Positioned around the stud M in the socalled non-wearing zone of the heel but spaced inwardly from the periphery are replaceable pro- 2 jecting nails or pins l5, l5. l5 having roughened upper surfaces.

The under surface of the lift l2 has a central metal socket l6 and positioned around said socket are spaced openings H. The socket and openings ll, ii, i! are positioned so that when in position over the heel I I, they are in alignment with the central stud I l and pins l5, 15, I5, respectively, and a little pressure by the hand will force the stud into the socket and the pins into the openings. The roughened surfaces of the pins will engage the walls of the openings and jointly with the stud and socket securely hold the lift on the heel.

An important feature of my invention is the additional means for securing the lift to the heel. This comprises spaced cavities l8, l8, l8 formed in the upper surface of the heel in the so-called wearing zone indicated in Fig. 1 which are in alignment with similar cavities l9, l9, [9 formed in the under surface of the lift in the wearing zone. The surfaces of the heel and lift containing these cavities are coated with a thin coating of rubber cement before the lift is pressed into position and when the lift is pressed into locking position on the heel the cement will ooze into the aligned cavities such as indicated at 20 in Fig. 6 and will be effective with the interlocking stud, socket and openings in securely holding the lift on the heel.

Another feature of the present invention is a metal insert or plate 2! countersunk in the front edge of the outer surface of the heel H which when the lift [2 is in position on the heel leaves a crack or opening between the heel and lift for the reception of the knife edge of a tool thereby permitting the easy removal of the lift for replacement by a new lift. The insert prevents damage to the heel.

The improved lift l2 may be either leather or rubber and the heel ll may be leather or wood as desired.

It will also be understood that the number of interlocking pins and openings and the number of cavities may be varied with the size of the heel and when the wearing surface of the heel is extremely narrow, fewer of such pins, openings and cavities can be used.

The adjacent surfaces of the heel and lift may also be roughened if desired to more securely hold them together.

It will be understood that by placing the fastening pins in the non-wearing zone, when the wearing surface of the lift has worn down, such pins will not be damaged and will be in condition for insertion into the openings of a new lift.

I claim:

1. In a ladys shoe, a heel portion having spaced cavities formed in its upper surface, a central stud projecting from said upper surface, a replaceable lift portion on said heel portion, a socket member on the lower surface of said lift and adapted to interlock with said central stud for detachably holding the lift on the heel, said I lift portion having spaced cavities formed on its lower surface and adapted to align with the cavities on the heel, said aligned cavities forming pockets for receiving cement for assisting said interlocking members to hold the lift on the heel.

2. In a ladys shoe, a heel portion, a central stud projecting from the upper surface of said heel portion, a replaceable lift portion on said heel portion, a socket member on the lower surface of said lift and adapted to interlock with said central stud for detachably holding the lift on the heel and pins projecting from the upper surface of said heel portion, the lower surface of said lift being provided with openings adapted to receive said pins to assist said interlocking members to hold the lift on the heel portion, the upper surface of said heel portion and the lower surface of said lift [being formed with aligned cavities for receiving cement for assisting the interlocking members and pins and openings in holding the lift on the heel.

3. In a ladys shoe, a heel portion having spaced cavities formed in its upper surface, a central stud projecting from said upper surface, a replaceablelift portion on said heel portion, a socket member on the lower surface of said lift and adapted to interlock with said central stud for detachably holding the lift on the heel, a. plate member countersunk in the upper surface of said heel at its front edge for engagement by a lift removing tool, said lift portion having spaced cavities formed on its lower surface and adapted to align with the cavities on the heel, said aligned cavities forming pockets for receiving cement for assisting said interlocking members to hold the lift on the heel,

4. A heel for a ladys shoe comprising a main body portion having spaced cavities formed in its upper surface at the rear and to one side thereof,

a central stud projecting from said upper surface, a replaceable lift portion on said body portion, a socket member on the lower surface of said lift and adapted to interlock with said central stud for detachably holding the lift on the body, pins projecting from the upper surface of said body remote from said cavities, said lower surface of said lift being provided with openings adapted to receive said pins to assist said interlocking members to hold the lift on the body, said lift portion having spaced cavities formed on its lower surface remote from said openings and adapted to align with the cavities on the body, and a plate member countersunk in the body portion at its front edge for engagement by a lift removing tool, said aligned cavities forming pockets for receiving cement for assisting said interlocking members and pins and openings to hold the lift on the body.
